Q: How can I get the recordings off the iPhone?

Currently this is not possible unless you have a hacked iPhone. One of the next updates will include a better solution! Stay tuned.

Q: But I have a jailbroken iPhone - where do I find the recordings?

You’re a hacker, just use “find / -name *.wav” ;)

Now seriously, the recordings generally should be stored in /var/mobile/Applications/*/Documents/recordings unless you really hacked on your phone in ways we didn’t yet know about.
